I was really excited to get this downstem since I’ve broken several glass ones and liked the fact that it wouldn’t shatter. The build quality of this downstem is great and it works but it doesn’t work how I expected it to. This downstem definitely taints the flavor of your bud a bit. It adds a bit of a metallic taste. Also, the pull requires a fair bit more lung capacity. I assume this is because of the tiny screen at its base near the diffuser. Overall this thing works for if you’re in a pinch and don’t have any other downstem, but it ruins the flavor and is pretty tough to pull and clear. The invincibowl is wonderful though. One of the best purchases I’ve ever made.
